Bay Area Sunrises & Sunsets

Guerrero, who also is a member of the the Latino firefighters group, Los Bombers, said he is frustrated when his crews respond to emergency calls and have to wait to get the symptoms of the awaiting patient or victim.

"Well definitely there's a frustration level because you can only treat what you see," he said. "A lower type of service."

Deputy Chief Robert Sapien said the department has seen no significant issues with the translation service. But Sapien said he agrees with the concerns from worried firefighters.

"We share the concern," he said. "We want to deliver service to the best ability we can."

Sapien is now working to improve the department's bilingual program.

"I think it's really time for a total program review and some evaluation and values checking to see how we want to provide our service," he said.
